PROBLEM TO BE SOLVED: To provide a waste heat recovery system for gas turbine cogeneration equipment, in which waste heat from cooling water of a refrigerator or an auxiliary machine cooling water system can be used for a water supply system of a waste heat recovery boiler as a steam generating device. SOLUTION: The waste heat recovery system for gas turbine cogeneration equipment, comprises: a gas turbine 1 having intake air cooler 5; the waste heat recovery boiler 2 as a steam generating device generating the steam from the exhaust gas of the gas turbine; the steam system 20 supplying the steam generated in the waste heat recovery boiler 2; the refrigerator 6 disposed to the cooling water system 24 of the intake air cooler 5 to cool the cooling water; a cooling water system 26 having a cooling tower 7. The cooling water system 24 of the intake air cooler 5 is connected with the cooling water system 26 of the cooling tower 7 with feeding water connection pipe 31 and a return water connection pipe 32, and control valves 12, 13 mixing all of or a part of the cooling water of the cooling water system 26 are disposed thereto. A control device 15 which uses output of an inlet cooling water thermometer controls to open/close the control valves 12, 13. COPYRIGHT: (C)2007,JPO&INPIT |
